Wl ETALLlC RAILWAY-TIE.

SPECIFICATION forming part of Letters ratent no. 706,788, dated August12, 190e. Application filed February 11,1902. i Serial No. 93,578. (Nomodel.)

To all whom it may concern:

Be it known that I, JOHN FRANCIS WEIS- BROD, a citizen of the UnitedStates, residing at Allegheny, in the county of Allegheny and State ofPennsylvania,have invented a certain new and useful Improvement inMetallic Railway-Ties, of which the following is a full, clear, andexact description.

This invention relates to metallic ties for use in the construction ofrailways.

In carrying out the inventionI use metal, rolled, pressed, or otherwiseproduced, of channel shape bowed longitudinally, a pair of such bowedchannels being united back to back and having stay-pieces interposedbetween their flanges at the points where the rails are to be laid.Combined with such a tie are rail-Clamps of peculiar construction. Thechannels are set edgewise in use and so as to permit the entrance of theballast between the flanges, thereby the more securely to ern'- bed thetie and likewise support it.

Having thus stated the principle of my invention, I will `proceed now toset forth the best mode in whichI have contemplated applying thatprinciple and then will particu-1 larly point out and distinctly claimthe part,`

improvement, or combination which I claim as my invention.

In the accompanying drawings, illustrating my invention, in the severalfiguresof which like parts are similarly designated, Figure l is aperspective view of a portion of a railroad-track containing thefeatures of my invention. Fig. 2 is a perspective view of one of theduplex ties detached. Fig. 3 is a perspective view showing the means forfastening the rail to the tie. Fig. 4 is a perspective view showing theleft-hand fasteningclamp. Fig. 5 is aperspective view showing theright-hand fastening-clamp. Fig. 6 is a cross-section of a rolledChannel. Fig. 7 is a cross-section of a pressed-steel channel.

Referring to Fig. 2 especially,l and 2 are appropriate lengths ofchanneled metal, rolled, pressed, or otherwise produced and bowedlongitudinally and united back to back by rivets or otherwise, so thattheir outer ends flare away from one another, and so that their upperflanges form bearing-surfaces to receive the rails, and their lowerflanges form bearing-surfaces to come into contact with the road-bed. Ifdesired,rthe upper flanges may be provided with recesses 3 at oppositeends, spaced apart in accordance with the track-gage to receive thebases of the rails, and in line with the rail-receiving surfaces andbetween the flanges I interpose stays 4, which may be sections of I-beamor T-beam riveted to the lower flanges or to both flanges, if desired,to afford a rigidity and stiffness equal to a solid tie at the points ofgreatest pressure. When such ties are laid, the spaces between theirflanges are filled with the ballast or road-bed material, as indicatedin Fig. l, and kthus the ties are anchored in the roadbed securely andimmovably in any direction, the backs of the channels abutting againstthe material of the road-bed, preventing movement in the direction ofthe length of the road, and the stays Ll resisting movement in thedirection of the length of the ties. The spread between the ends of thechannels may be of any desired extent, and preferably is such as topermit of the use of one of these double or duplex ties for three of theordinary straight ties.

In order to provide for fastening the rails to the ties, I use a pair ofclamps, one of which, 5, preferably the outer, is composed of a flatplate of metal adapted to be bolted through holes 6to the tie and havinga vertical portion 7 projecting beyond the tie and. which abuts againstthe edge of the base of the rail, and a substantially horizontal portion8 at the top of said vertical portion which overlaps the base of therail on one side, While the other clamp 9,which by preference isarranged on the inside of the track, has a transverse slot lO, so as tobe capable of adjustment toward and from the rail by means of its bolts,which engage holes 1l in the tie. This inner fastening member 9 has alsoa vertical portion 2, abutting against the edge of the base of the rail,and a substantially horizontal portion 13, which overlaps upon the topof the base of the rail, and the two vertical portions 7 and 12 arepreferably connected by a bolt 14 near their outer ends. These fasteningdevices will be of such character as not to interfere with thefish-plates or rail-joints, and they afford a ready means for securingthe rails to the ties and may be as readily displaced for purposes ofrepair. The provision ICO of the slot 10 in one or both of the clampsand at one or both of the bolt-holes admits of the adjustment of theclamps to the rails and the sh-plates.

What I claim is- 1. A rail-tie, composed of similar metallic channels,bowed longitudinally, set on edge, and united back to back.

2. A rail-tie, composed of two pressed-steel channels, bowedlongitudinally, arranged on edge, and united back to back.

3. A rail-tie, composed of similar channels, bowed longitudinally, seton edge,united back t0 back, and having their outer ends aring, andstays interposed between the flanges at the points of support of therails.

4. A rail-tie, composed of longitudinallybowed channels united back toback, and provided with rail-seats in their upper flanges, and staysinterposed between the anges beneath the rail-seats.

5. A metallic rail-tie, combined withv railfastenings, each of which hasa Hat portion scenes adapted to be bolted to the tie, a vertical portionprojecting beyond the tie to abut against 25 the base of the rail, andasubstantially horizontal portion on said vertical portion to overlapthe base of the rail, one of which fastenings is adjustable.

6. A metallic rail-tie, combined with rail- 3o fastenings, each of whichhas a flat portion adapted to be bolted to the tie, a vertical portionprojecting beyond the tie to abut against the base of the rail', and asubstantially horizontal portion on said vertical portion to over- 3 5lap the base of Ithe rail, means to adjust the fastenings, and across-bolt engaging the vertical portions of the fastenings beneath therail-base.

In testimony whereof I have hereunto set 4o my hand this 10th day ofFebruary, A. D. 1902.
